Question $2(25$ pts$).$ We have a suspension of pure liquid o$-$xylene $(M_E=106\frac{g}{m}ol),$

with a liquid vapor pressure of ${8\mathrm{.}7}^{**}{10}^3$atm, and an activity coefficient in water of

${3\mathrm{.}37}^{**}{10}^4.$ Starting with the fugacity equality $f_{Ew}=f_{Ee}$ where $e$ is the pure xylene phase,

derive and solve for an expression for the solubility $(m\frac{g}{L}$ of o$-$xylene in water.
